I hope this helps . See Phrogz answer here: Nokogiri, open-uri, and Unicode Characters which I think correctly describes what is happening for you. In summary, for some reason there is an issue passing the IO object created by open-url to nokogiri. Instead read the document in as a string and give that to Nokogiri, i.e.:
code :
require 'nokogiri'
require 'open-uri'

open("https://www.youtube.com/watch?v=QXAwnMxlE2Q") {|f|
  p f.content_type     # "text/html"
  p f.charset          # "UTF-8"
  p f.content_encoding # []

doc = Nokogiri::HTML(open("https://www.youtube.com/watch?v=QXAwnMxlE2Q"))
puts doc.title.to_s # =>  NTV interview foreigners in Japan æ¥ãã¬å¤äººè¡é ­ã¤ã³ã¿ãã¥ã¼ English Subtitles è±èªå­å¹ - YouTube

doc = Nokogiri::HTML(open("https://www.youtube.com/watch?v=QXAwnMxlE2Q").read)
puts doc.title.to_s # => NTV interview foreigners in Japan 日テレ外人街頭インタビュー English Subtitles 英語字幕 - YouTube
doc = Nokogiri::HTML(open("https://www.youtube.com/watch?v=QXAwnMxlE2Q"), nil, "UTF-8")

this one helps. You need to wait for the table to load. Simply adding a delay made it work for me:
code :


table = driver.find_element_by_id('quotesFuturesProductTable1')
DEC 2014 168.025
FEB 2015 166.900
APR 2015 164.775

AUG 2015 152.900
OCT 2015 154.100
DEC 2015 154.250

I hope this helps . If you are sure that html in comments is valid you can simply remove them and then parse resulting html:
code :
String html = doc.html(); 
html = html.replaceAll("<!--", "").replaceAll("-->", ""); 
doc = Jsoup.parse(html);
